Work requirements and production process of coal fired boiler blowerMar 22, 2018

During the operation of the coal fired boiler blower, when the impeller is driven by the motor to rotate, the gas filled between the blades will rotate along with the impeller. The coal-fired boiler blows the gas from the inter-blade channel under the action of centrifugal force. Throw out and send the gas out of the impeller outlet.

The outflow of gas from a coal fired boiler blower will, to a certain extent, directly cause a vacuum in the form of its impeller space, so that its external gas will be automatically added to the impeller for supplementation. Since its fan is constantly working, it will directly use its gas. Suction in and out, this will create a continuous flow of gas, which will create a continuous work.

In the process of making the coal fired boiler blower, the fan is mainly driven by the fan to rotate the wind to generate wind. Although it is more complicated than the fan, there is no difference in essence. The role of the blower is determined by the location where they are installed. The former is located at the back end of the boiler and blows air to the flue outside the boiler. It generates negative pressure on the furnace and plays a leading role in the flue gas. It is called the induced draft fan. The latter is located at the front of the boiler and blows air into the boiler. So called a blower.

The noise of draft fans and blowers of coal-fired boiler fans is generally around 90 decibels. During the operation process, the temperature of the flue gas from the boilers it delivers will be as high as 180 degrees. The entire equipment is mainly used for its closed sound insulation, which will lead to poor heat dissipation. The motor temperature is too high and even burns the motor. Therefore, the combination of fan noise reduction and energy saving is combined in the process.
